New Federal Wire Rope Standard Published

A new federal specification for wire rope and strand, RR-W-410F, was published in December 2007. This standard supersedes the previous federal standard, RR-W-410E, published in 2002.

The standard covers the more common types, classes, constructions, and sizes of wire rope and strand that are suitable for federal government use. This includes Type 1 general purpose ropes, Type 2 elevator ropes, Type 3 marine cables, Type 4 miscellaneous, Type 5 auxiliary wire strands, and Type 6 small cords.

An important change to the standard for crane users is that ASTM A1023/A1023M, the standard specification for stranded carbon steel wire ropes for general purposes, is now incorporated by reference into the federal specification as it relates to all general purpose ropes. The A1023 standard was published in 2002 and revised in 2007 with input from the Wire Rope Technical Board.
